:Mevalonate diphosphate decarboxylase (MDD) is an important enzyme required for the biosynthesis of cholesterol and other isoprenoids in mammals, bacteria, yeast and fungi <ref name = "Byres"> 17583736 </ref>. MDD is a member of the GHMP (Galactokinase, Homoserine kinase, mevalonate kinase and phosphomevalonate kinase) enzyme family, and is responsible for the conversion of mevalonate diphosphate to isopentenyl pyrophosphate with the help of 1 ATP molecule<ref name = "Byres"/> <ref name = "Voynova"> 18823933 </ref>. | :Mevalonate diphosphate decarboxylase (MDD) is an important enzyme required for the biosynthesis of cholesterol and other isoprenoids in mammals, bacteria, yeast and fungi <ref name = "Byres"> 17583736 </ref>.

Even though the kinases in the GHMP family differ in quaternary structure and ability to bind a wide variety of substrates, they share a characteristic alpha/beta fold and similar sequences <ref name = "Byres"/> <ref name = "ByresMartin"> 16511101 </ref>. Some GHMP kinases exist as dimers, some as tetramers and some as monomers <ref name = "Byres"/>. The amino acid residues in MDD are highly conserved across all species, indicating the specific important activity of the enzyme <ref name = "Byres"/>. | ||
